Dressed-fchannelahthe outer sidef of: each arm and in whichthe. angle memberV 5 is seated-',soi'asfto lie slightly below the .Louter piane of each farm.

Each; of the: intermediate frame members` I corresponds in transverse cross-section to .the

0 cross-section offthet arms-3'. 31 -of the corner members 3', so thatwhen the intermediate meinbers are arranged between the opposing arms 3', 3 of two corner members 3, 3. they will form continuations of the arms.

Figure 2 is a. view in elevation of the construc- 55 At the opposite side of the frame l. there il 3 provided a second set of frame members respectively designated 9, each of which is longer than the intermediate members 4 at the opposite side of the frame, so that each member 9 overlaps upon the opposing arms 3 of each adjacent pair of corner members 3. As will be seen from reference to Figure 3 of the drawing, the form of each member 9 is substantially a duplicate of the respective intermediate members 4, including the marginal flanges l0, I at the outer and inner edges, respectively, and the depressed central portion i i. However, the width of the respective members 9 is slightly less than that of the members 4 and arms 3', 3' of the corner members 3, so that the flanges l0, l) of the members 9 will lie Within the iianges l, 'i of the members 4 and arms 3', said flanges l', 1 and I0, ,Ill overlapping each other when the members are assembled together. Thus, the screen wire or mesh 2 is adapted to be iirmly gripped between the flanges l, l of the framemembers 3 and 4 on one side of the frame, and the flanges I0, I0 of the members 9 at the other side of the frame, as clearly shown in Figure 3, thereby eiiectively stretching the screen wire or mesh 2 in all directions as the frame members are pressed together, and assuring a positive and secure attachment of the screen wire or mesh 2 to the frame r In order to hold the frame members in assembled position, theymay be fastened together by any suitable fastening means such as rivets f2, said rivets passing through the frame members at 'both ysides of the frame, as well as through the screen wire or mesh 2 which is disposed intermediate thev frame membersat its outer edges.

ranged at opposite sides of the frame, all of said frame members being substantially channelshaped in transverse cross-section, with the channels of the members of the respective sets on opposite sides of the frame disposed in opposed relation to each other and fitting one within the other. Thescreen wire or mesh which is mounted between the frame members vof the respective sets is clamped between the opposing frame members,

"and gripped by the overlapping of the opposing frame members along the inner as well as the outer edges of the -iframe members. The clamping or gripping action is 'thus in the nature of a double-grip upon the screen wire or mesh.

By making the frame members of aluminum, the frame assembly will be light in weight, yet strong and durable, neat and attractive in appearance, easy to assemble and install, and readily lends itself to mass production in accurate sizes` and shapes. VBy reason of the channelshaped cross-section of the frame members, sufricient rigidity or stiiness. of the members is assured, and consequently, the frame assembly will not bend easily, sag, or get out of shape, even when subjected to rough handling. Obviously, the construction readily lends itseli to the making of frames of various sizes simply by employing and assembling the corner members 3 with intermediate members 4 and opposing members 9 of different lengths, according to any given Window size.

While the speciiic details have been herein shown and described, the invention is not confined thereto as changes and alterations may be made without departing from the spirit thereof as defined by the appended claims. l

What I claim is:

1. A frame structure for window screens and the like, comprising a plurality of frame members arranged in the form of a rectangle and forming one side oi the frame, and a plurality of frame mentioned frame members to form the opposite side of the frame, each of said frame members having marginal fianges `along the inner and outer edges, respectively, thereof, with the flanges of the opposed frame members overlapping upon each other, the frame-members which form one' side of the frame includinga right-angle corner member at each corner of the frame, and an intermediate straight member disposed between the opposed arms of each adjacent pair of corner members and coextensively aligned with said arms, and the frame members which form thev opposite side 'of-the frame each having the form of a single straight: member of greater length than the intermediate straight members at the nist-mentionedv side ofv the frame, so as to substantially. overlap the opposed arms. of eachade jacent -pair of corner memberswhen vassembled in opposed ,relation to thgcorner members and intermediatemembersip l y p 2. A window-screen assembly, comprising come plementary frame members of channel-shaped form arranged -in opposed relation toeach other, with the marginal lianges of the opposing members-extended in overlapping relation to each other at the inner andouter edges, respectively, thereof, the frame members at onev side of the assembly including right-anglefcorner members and intermediate members aligned lwith and abutting each pair of corner members, and the frame members of the opposite side of the asf sembly being continuous from each corner mem-f berto the next and substantially overlapping the corner members at their respective opposite ends, aflexibleforaminous screen disposed between the opposing frame members, said screen' rextending to the extreme outer marginal edges of all the frame members with its marginal edges gripped between the overlapping iianges of the opposed frame members, 'and means for securing the opposing irame memberstogether, with the screen gripped therebetween. p
